DIAGNOSTICS OF FAULTS DURING TESTING OF TURBINE PLANT Russian patent published in 2019 - IPC G01M15/14 

FIELD: turbines or turbomachines.

SUBSTANCE: described is a method of diagnosing faults during testing of a turbine installation in a turbine testing system, wherein the turbine plant comprises a plurality of turbine components and turbine sensors, and the turbine test system comprises a plurality of test sensors. Described method comprises steps of: (a) obtaining measurement data from turbine sensors and test sensors, (b) calculating at least one parameter value based on measurement data, (c) determining deviation of measurement data and at least one parameter value by comparing measurement data and at least one parameter value with given control data and (d) comparing a certain deviation with a plurality of predetermined fault signatures for fault detection, wherein a plurality of predetermined fault signatures comprises a first set of fault signatures and a second set of fault signatures, wherein the first set of fault signatures corresponds to faults of turbine sensors and/or faults of test sensors and assumed working components of turbine, and the second set of fault signatures corresponds to faults of turbine components and to supposed serviceable turbine sensors and test sensors.

EFFECT: this method provides the possibility of distinguishing faults that can be immediately eliminated, and faults that require additional inspection or repair of the turbine plant.
